System Bios Cacheable - MSI ATX BX2 User Manual

SDRAM Configuration by
Choose SPD, the SDRAM time will load from the DIMM EEPROM
value. Choose manual, the value will be set by SDRAM Ras-to-CAS Delay,
SDRAM RAS Precharge Time, and SDRAM CAS Latency Time. The
settings are SPD and Manual.
If the DIMM is without EEPROM or over CPU clock, then set this
item to Manual. Set SDRAM Ras-to-CAS Delay, SDRAM RAS Precharge
Time, and SDRAM CAS Latency Time to 3.
SDRAM RAS-to-CAS Delay
This item sets the relative delay between the row and column address
strobes from DRAM (SDRAM). The settings are 2 or 3.
SDRAM RAS Precharge Time
Defines the length of time for Row Address Strobe from DRAM
(SDRAM) allowed to precharge. The settings are 2 or 3.
SDRAM CAS Latency Time
You can select CAS latency time in HCLKs of 2 or 3. The system
board designer should set the values in this field, depending on the DRAM
installed.
DRAM Data Integrity Mode
This item will automatically detect your DIMM for ECC. The set-
tings are Non-ECC or ECC.

System BIOS Cacheable

Select Enabled allows caching of the system BIOS ROM at F000h-
FFFFFh, resulting in better system performance. However, if any program
writes to this memory area, a system error may result.
